Description:
Abstract: Data set contains 2.5km by 2.5km digital orthophotography mosaics. The digital orthophotos in this series have a nominal ground resolution of 1 meter. The digital orthophoto mosaics are three band, 8-bit GeoTIFFs with pyramids and are color balanced to be uniform while still maintaining as much of the original color and appearance as practical. The source imagery was flown on February 6-7, 2010 with a WILD camera with a focal length of 153.28mm. The film was captured by NOAA at a negative scale of 1" = 2,500' or a nominal scale of 1:30,000. Aerotriangulation was performed in BINGO as full bundle block adjustments. The project area extends from Big Lagoon to Navaree Beach and includes Pensacola Bay, Escambia Bay, and East Bay; as well as portions of Santa Rosa Sound, and Santa Rosa Island and various small bays and tributaries to the bays.
Purpose: Ortho-rectified mosaic tiles are an ancillary product of NOAA's Coastal Mapping Program (CMP), created through a wider Integrated Ocean and Coastal Mapping initiative to increase support for multiple uses of the data.
Supplemental_Information: The ground sample distance (GSD) for each pixel is 1.0 meter.

Data_Set_Credit: This data set was developed for NOAA by Photo Science, Inc..
Native_Data_Set_Environment: The data set was created on Windows XP operating system clients running ZI Imaging's Ortho Pro, ArcGIS, MicroStation and Socet Set application.
Data_Quality_Information:
Logical_Consistency_Report: Imagery was collected with a WILD camera with a focal length of 153.28mm. Aerotriangulation was performed in BINGO as full bundle block adjustments. Imagery was orthorectified to a USGS DEM using Z/I Intergraph OrthoPro. Seamlines were drawn and then mosaics were also cut using Z/I Intergraph OrthoPro. Mosaics were checked to ensure they were free of artifiacts, fiducial marks, film tilting or frame borders.
Completeness_Report: The extent of image coverage is limited to the acquired flight lines which were planned to map the shoreline and therefore may not include all areas within the bounding coordinates.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: The horizontal positional accuracy and the assurance of that accuracy are dependent upon the accuracy of the data inputs to the rectification process. These data inputs include the digital elevation model (DEM), accuracy of control, and methodology used to georeference the imagery that meet NOAA's Coastal Mapping Program standards.
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: 0.77
Horizontal_Positional_Accuracy_Explanation: These data are accurate with a 95% circular error confidence level.

Process_Step:
Process_Description: Photo Science's digital orthorectification process relies on four primary production data sources including digital aerial imagery, camera calibration data, ground and airborne control/aerotriangulation data, and the existing DEM as described above. Photo Science rectified all of the image frames to minimize the effects of radial displacement and to ensure radiometric consistency. The rectification process employed a cubic convolution re-sampling method, which sharpens the edges of linear features by sampling 16 of the closest pixels and performs a weighted adjustment. Intergraph OrthoPro software was used to accomplish the rectification of the individual frames. Mosaicking was also accomplished using OrthoPro software. Image blocks were processed using two distinct tonal matching functions. Each image was processed to remove any hotspots in the middle of the frame. During the collection of aerial imagery, more light enters the lens from directly below the camera than does from the corners of the frame. Even though filters are designed to minimize this effect, some hotspots still can occur. Additionally, all of the frames underwent a histogram comparison process and then were matched to provide a seamless tone image. For optimal production performance Photo Science initiated an automatic seamline creation strategy for image mosaicking. Auto-generated seamlines are reviewed and manually adjusted to avoid buildings and other features depicting discontinuity. The mosaic was then reprocessed using manual seamlines to maximize image quality. During the mosaicking process, seamlines were feathered to provide a smooth transition from one image to another. Photo Science utilized a combined automated / manual methodology for maximum cost efficiency and image quality. Tonal matching was accomplished by comparing pixel values in the overlap area of all images. The software modified the histograms of the individual images to achieve an overall mosaic, which will had a uniform tone throughout the images. Orthomosaic files were tiled to a ground distance of 2.5 km by 2.5 km with a ten (10) meter buffer (overlap) around all four edges of the tile. The final format of the tile index was a polygon shapefile projected to NAD 83 in geographic coordinates.
